Limits worth knowing in Otto

  • It is a Chrome extension: there is no desktop or mobile app, and the vendor gives no date for the mobile app on its roadmap.
  • The free version caps scheduled blocking at 2 rules, autoblock at 1 rule, the task timer at 3 tasks of 15 minutes and analytics at 7 days.
  • The one-year license does not carry on: when it expires, Pro features stop and the extension drops back to the free version.
  • There is no free trial of Pro, though refunds are given within 14 days. The web version is a plain timer without blocking.
